In general, packaging materials which encapsulate light emitting diodes (LEDs) and microelectronic devices offer barrier protection against several environmental hazards such as water and ionic contaminants. However, these encapsulants may provide pa

Tarnishing of the reflective silver layer in LED packages is an important failure mechanism, leading to both a decrease in luminous flux by up to 75% and a change in color spectrum.

The effect of contact with PTFE tape on the moisture cure of an alkoxysilicone sealant

Autor: C Subramanian, F. De Buyl, John Comyn

Publikováno v: International Journal of Adhesion and Adhesives. 22:331-336

PTFE tape can be placed in contact with silicone glazing sealants, before they cure by reaction with water vapour from the atmosphere. Upon removal of the tape after cure, a smooth and tack free silicone surface remains. This phenomenon has been inve

Mobility of water and alcohols in a silica reinforced siloxane network

Autor: John Comyn, F. De Buyl

Publikováno v: European Polymer Journal. 37:2385-2391

The water vapour permeability coefficient (P) of a silica reinforced siloxane network has been measured in the temperature range 5–45°C. P is independent of humidity and stretching of the material, but a plot of logP against reciprocal absolute te

Diffusion of adhesion promoting and crosslinking additives in an uncured silicone sealant

Autor: T.P. Comyn, John Comyn, F. De Buyl

Publikováno v: International Journal of Adhesion and Adhesives. 23:495-497

A method has been devised for measuring the diffusion coefficient D of additives that act as adhesion promoters and crosslinking agents in uncured silicone sealants. This has been used to measure D for tetra-t-butyltitanate (TBT) and isobutyltrimetho
